Country duo Thompson Square has been forced off the road temporarily due to a vocal illness that has stricken one of its members.

Keifer Thompson says in a new statement that he is suffering from a "very serious vocal condition" and has been ordered to stop singing, bringing their tour in support of current album "Just Feels Good" to a halt.

Thompson reveals that doctors actually urged him to go on vocal rest weeks ago, but that he and wife Shawna Thompson chose to continue performing "while I remained completely silent offstage in an effort to heal."

But the unspecified illness has lingered and the band has decided to cancel this weekend's shows "in an effort to heal internally."

The cancellations include tonight's headlining show in Glen Valley, Va. and the following four dates on the Luke Bryan Dirt Road Diaries tour (Cole Swindell replaces them):

May 30 - Canandiagua, NY

May 31 - Hartford, CT

June 1 - Camden, NJ

June 2 - Boston, MA

"Words cannot express how devastated we both are to bring this news to our fans," Keifer Thompson says. "We hope that you will understand what a difficult decision this has been and know that we can't wait to get back out on the road and make it up to you as soon as possible."

The husband-wife duo released their sophomore album "Just Feels Good" in late March, debuting at No. 4 on the Top Country Albums chart. Lead single "If I Didn't Have You" topped out at No. 7 on Hot Country Songs but has since fallen to No. 22.
